Answer: Resistance is the ratio of potential difference to the current.
Explanation: In electronics, resistance is defined as the obstruction in the path of current flowing in a circuit.
According to the Ohm's law the relation between resistance, current and potential difference is expressed as:
Voltage drop across the terminals of a circuit = Current flowing in the circuit [tex]\times[/tex] resistance offered by the circuit.
V = I [tex]\times[/tex] R
Here V is in Volts
I is in Ampere
R is in Ohms
So, resistance can be defined as the ratio of potential difference to the current.
